HELP! I’m actually scared

I’m so scared!!!! Ok idk what’s going on but one day my vagina just started itching!!!!! yes I am sexually active and recently had sex with a newish partner without a condom but then like a week later my vagina started itching! Also I don’t know if this is related at all but I recently bought a new bikini and tired it on and a couple hours later after trying it on I started to itch. Do you guys have any clue as to what’s going on. And don’t worry I have an appointment scheduled asap to get it checked out but in the mean time I’m just very worried. If you have any information OR anything!!!! Plz help 😭
